The INIU Power Bank is a compact and lightweight option for those needing a portable charging solution. With a capacity of 10,000mAh, it offers a decent amount of power for recharging devices. What stands out is its small size and light weight, being 30% smaller and 15% lighter than similar capacity power banks, making it highly portable. Its charging speed is impressive, equipped with a 45W fast-charging capability that can charge an iPhone 15 to 60% in just 25 minutes, which is useful for quick top-ups.

The power bank features multiple ports, including two USB-C ports and one USB-A port, allowing you to charge up to three devices simultaneously. This versatility can be handy in situations where multiple devices need power at once. The USB-C port can be used both for input and output, providing more flexibility compared to power banks that only allow for USB-C charging.

Compatibility is broad, supporting popular devices like iPhones, Samsung phones, and Google devices, which makes it a versatile choice for a range of users. Additional features such as indicator lights for battery status and the inclusion of a USB-A to USB-C cable add to its convenience.

However, for users who require more power for longer trips, the 10,000mAh capacity might be limiting compared to larger power banks. While it's great for short outings or daily use, it may not suffice for extended travel without frequent recharges. The product's delivery is restricted outside mainland UK, which could limit accessibility for some customers.

The INIU Power Bank is ideal for those seeking a reliable, fast-charging option in a small, easy-to-carry design, making it a travel-friendly choice for everyday use.

Buying Guide for the Best Power Banks

Choosing the right power bank can make a big difference in how you manage your devices on the go. Power banks are portable chargers that allow you to recharge your electronic devices without needing a wall outlet. When selecting a power bank, consider factors like capacity, size, weight, charging speed, and compatibility with your devices. Understanding these specifications will help you find a power bank that suits your lifestyle and meets your charging needs.
Capacity (mAh)Capacity, measured in milliamp hours (mAh), indicates how much charge a power bank can store. This is crucial because it determines how many times you can recharge your device. Power banks with lower capacity (around 5,000 mAh) are suitable for small devices or emergency use, while mid-range capacities (10,000-20,000 mAh) can charge smartphones multiple times. High-capacity power banks (20,000 mAh and above) are ideal for tablets or multiple devices. Choose a capacity based on how often you need to charge your devices and the types of devices you use.
Size and WeightThe size and weight of a power bank affect its portability. Smaller, lighter power banks are easier to carry and fit in pockets or small bags, making them ideal for everyday use or travel. Larger power banks may offer more capacity but can be bulkier and heavier, which might be less convenient for carrying around. Consider how often you'll be carrying the power bank and whether you prioritize portability or capacity.
Charging SpeedCharging speed refers to how quickly a power bank can recharge your devices. This is determined by the output current, measured in amperes (A). Standard charging speeds are around 1A, which is suitable for most smartphones. Faster charging speeds, like 2A or higher, are better for tablets or quick charging needs. Some power banks support fast charging technologies, which can significantly reduce charging time. Choose a power bank with a charging speed that matches your device's requirements and your need for quick recharges.
Number of PortsThe number of ports on a power bank determines how many devices you can charge simultaneously. Single-port power banks are sufficient for charging one device at a time, while multi-port options allow you to charge multiple devices, which is useful for families or tech enthusiasts with several gadgets. Consider how many devices you typically need to charge at once and choose a power bank with enough ports to accommodate your needs.
CompatibilityCompatibility refers to whether a power bank can charge your specific devices. Most power banks come with USB ports, which are compatible with a wide range of devices. However, some may offer additional ports like USB-C or Lightning for specific devices. Ensure the power bank you choose has the right ports and cables for your devices. If you have devices with different charging requirements, look for a versatile power bank that can handle various types of connections.
Additional FeaturesSome power banks come with extra features like built-in cables, LED indicators, or wireless charging capabilities. Built-in cables can be convenient, eliminating the need to carry extra cables. LED indicators show the remaining charge, helping you manage power usage. Wireless charging allows you to charge compatible devices without cables, offering more convenience. Consider which additional features might enhance your user experience and choose a power bank that offers those benefits.
